this relict species. 
Methods 
Most of the results reported here are based on field observations 
made from July 1970 to June 1971. For some behavioral observa- 
tions, spiders were kept in cardboard boxes in a humid basement 
room. The open sides of the boxes were covered with transparent 
plastic wrap. A headlamp covered with a red plastic “filter” was 
used for observing behavior at night. 
I collected H. thorelli in the following localities in North Caro- 
lina: Buncombe County — 3 mi S of Dillingham, Pisgah National 
Forest (females). Graham County — Joyce Kilmer Memorial 
Forest (egg cases). Haywood County — Sherwood Wildlife Man- 
agement Area, 13 mi SE of Waynesville (immatures). Jackson 
County — Cullowhee Mountain, 8 mi S of Cullowhee ( immatures, 
egg cases) ; Highway 107, 2 mi N of Glenville (immatures, egg 
cases) ; Little Mill Creek, 5 mi S of Tuckaseigee (males, females) ; 
Mull Creek, Caney Fork Game Area (males, females, immatures, 
egg cases) ; Tanassee Creek Reservoir, 12.5 mi SE of Cullowhee 
(immatures) ; Wayehutta Creek, 2 mi NE of Cullowhee (male, egg

Cherokee and Henderson counties, North Carolina and in Blount 
and Sevier counties, Tennessee. J. Dan Pittillo collected a mature 
male at Yonah Mountain, White County, Georgia. 
Repeated observations were made in the following localities where 
large populations of >H. thorelli were located: in Jackson County at 
Mull Creek, elev. 975 m (3200 ft), and Wolf Creek, elev. 730 m 
(2400 ft) ; and in Macon County at Dry Falls, elev. 1000 m 
(3300 ft).
